I have had the freezing problem twice and at first thought that it might be that my CF card could not keep up with the increased speed in burst mode, since then this problem has appeared on a few websites.

The battery level indicator also showed 50.00% when it was almost full ??

Removing and replacing the battery for a few seconds solved the problem.

I have re-installed FW 2.0.0 and removed the battery for a few seconds after completion as per the instructions. I missed this bit in the instructions first time round.

I have not had a chance to use the camera since.

The story continues, we went out today and had 3 more lockups, followed by 2 "Er 30's" and then it just died. Tried removing the CR1616 battery to do a reset and nothing.

It had a genuine Canon battery in & Canon Lens on so god knows what has happened. To say that I am not a happy bunny is a complete understatement as we are going away at the weekend so I need this like a bloody hole in the head.

To finish the story. I sent the 7D off to a Canon Repair Centre in the UK (CPS Silver Member) and got it back a week later after having the Printed Circuit Board (PCB) replaced at a total cost of £234.00 UKP (370.00 USD), they originally thought that it was the Shutter Mechanism causing the problem.

I dont know whether this problem exist with previous firmware, but, everytime I switch ON my 7D, i need to enable AF Micro Adjustment every time --> by lens. i does not stay enable even though i not changing the lens.

1) in flash menu, auto detecting lense length doesn't work, like 50mm lense suppose to let my 580ex zoom to 85mm, but it didn't happen, the flash stayed at 50mm2) my 50L, are completely two lenses when in low light and in ourdoor ambient light, in low light I have to add +10 in microadjust lense shift, in good light there is no problem.3) 7D might not be able to focus objects over 25 meters, but I don't have longer lense, for in 50L's f/1.2, all that is over 25meters might be in hyperfocal distance so I really couldnt tell, but my two 50/1.8 lenses couldn't focus over that distance, and that occurs 100%.

Image preview is faster, image rating is fine feature, but too deeply nested, so I don't use it. Max auto ISO works as expected, but I don't use it because to slow times are offerred when shooting with 85/1.8, I need to keep 1/200s and faster, no way to set up it ;( I don't use any other new features.

Only issue I've seen was my intervalometer (Promaster 3070 I believe) now only works as a standard remote shutter release and only if the device is in the off position. I can set the device for delay, exposure time etc, but the camera only takes a single image based on the last settings I used. Strange, but it's a 3rd party so I'm not exactly surprised and I guess it's a change you take.

No issue with mine, either. Note the instructions call for the main battery (or batteries if you have a grip, as I do) to be removed from the camera for a brief time to allow the new firmware to take full effect.

no problems but that the SET-Button and the Upperdial are absolutely functionless in the new Playback-Q-Menu are really annoying. The dial could easily be used to change between the options or to cycle truth pictures. And every time I rate a picture or protect one I hit the Set-button and nothing happens.Also this Menu is really not practical to protect or rate more than ONE picture because I have to close it go to next picture and have to reopen it ... CANON please that is far away from elegant !!!

My 7D quit displaying the shot image for the 4 second setting I had it on. After turning off then on again, it started displaying the shot image again. Otherwise, I believe it is performing better than it did prior to the firmware update.
